Following the Weekend Guangqi Group announced that the battery black technology was questioned by the industry, the market heat continued to ferment this week. Guangqi Group A and H shares have a significant differentiation, as of 5.43% of the closing, A shares, reported 13.20 yuan; H shares fell 8.10%, and reported HK $ 8.62.
Guangzhou Automobile brand Guangqi Yan is publicly announced that it is charged 8 minutes by a model of stone-based super fast charging, and NEDC standard battery life has reached 1000 kilometers. After the news announced, the Guangzhou Automobile Group A and H Shares rushed.
Zeng Qinghong, chairman of Guangqi Group, said in the "China Electric Automobile 100-member Forum 2021", GAC Group has made progress in graphene battery and silicon-negative high energy density battery development. Guangzhou Auto Pampnyl Super Quick Charge has now entered the real train test stage, the first mounting model is Aiionv, is currently doing a winter trial in the Heihe, which is sure to produce in bulk in September this year.
However, the academician of the Chinese Academy of Sciences, Ouyang Ming, is questioned. In his opinion, "can run 1000km, can be charged in a few minutes, and it is also very safe, the cost is also very low, such technology is not possible." "
In this regard, Gu Hui Nan, general manager of Guangqi Egyan New Energy Automobile Co., Ltd., then said that a thousand kilometers of battery car in 2021 will definitely launch the market, I hope you don't talk about technical breakthroughs and business promotion. Guangqi Yan announced again in the official interactive platform: Guangqi graphene super fast charging battery enters the real train test phase.
However, the question of experts still affect the capital market. Guangqi Group A and H shares will have a significant differentiation. On the evening, Guangqi Group announced that the graphene super fast charging battery and long-range silicon negative electrode battery is two different battery technology. The graphene-based super fast-charged battery and long-range silicon negative batteries have been carried out in accordance with the plan, and it is expected to be equipped with Aionv and Aionlx models in GAC ENA daily.
For graphene battery technology, Huachuang Securities indicates that graphene has a lower conductive threshold, which can greatly reduce the ohmic impedance of the battery to improve charging. When the large current is charged, the good thermal conductivity of graphene promotes the equalization of the temperature of the particle temperature, avoiding the life of life of the activated particles, which greatly helps high-power battery cycle life. At present, the world countries are accelerating the development and application of layout graphene, and graphene has been applied to the fields of batteries, screens, wearable devices, and future graphene industries will be at a high speed development phase.
However, Huatai Securities believes that the nature of the graphene battery is to increase the graphene as an additive, graphene is used in power batteries or enhances the charge and discharge ratio, but the energy density improvement is limited, how to balance the two performances to be verified. At present, the domestic graphene industry is still in the market introduction, the products are not mature, and the preparation cost is relatively high.
The agency also pointed out that because of balancing energy density, life, fast charge, security, cost-oriented performance indicators, battery material innovation requires long-term efforts and thickness, and has no big breakthrough in recent years. Currently commercial battery technological innovation belongs to minimally invasive new, including three aspects of the material system, system structure, and battery manufacturing. Therefore, rational should be reasonable to see the car companies claiming that new technologies can achieve comprehensive and superior performance indicators.
